INDICATING APPARATUS.

Specification of IQetters Patent.

Patented Aug. 22, 1916.

Application filed April 23, 1915. Serial No. 23,433.

To all whom it may concern:

Be it known that 1, CHARLES Gus'rArsoN, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in IndicatingApparatus, of which the following is a specification.

My invention relates to improvements in indicating apparatus, its objectbeing particularly to provide an apparatus to be carried by a carindicating the stops to the passengers, said apparatus beingelectrically actuated in the travel of the car.

To this end the invention consists in the features of construction andcombination hereinafter particularly described and claimed.

In the accompanying drawings forming part of the specification, Figure lrepresents a front elevation of my improved indicating apparatus; Fig. 2is a side elevation with the outer plate of the containing casingremoved. Fig. 3 is a detail view of a portion of a trolley wire andtrolley pole indicating a portion of the operating mechanism; Fig. 4 isa view opposite to Fig. 2; and Fig. 5 is a side elevation of a slightlymodified construction with part of the containing casing removed toillustrate the modification.

Referring to the drawings, A represents a containing casing for theindicating mechanism and associated means therefor, said casing beingadapted to be suitably supported at a proper position in the car toindicate the desired display matter, as the.

names of the stops, to the passengers. The indicating portion of theapparatus supported within the casing consists of a carrying roll 2having journal support 3 in a bracket 4 secured as by rivets 5 upon thebottom of the casing, and a similar roll 6 having journal support 7 in abracket 9, said bracket being secured as by rivets 10 to the top of thecasing. A driving roll 11 is mounted upon the shaft 12 intermediate ofthe carrying rolls. An indicating sheet 13 extends from one carryingroller to the other, intermediately running around the power roll andover idler rollers 14 and 15 arranged between the roll 2 and the powerroll and between the roll 6 and the power roll. Thus, it will beevident, by referring to Fig. 2, that the portion of the indicatingsheet standing between the idler rollers 14 and 15 will be inperpendicular position behind the transparent sightpane 16.

For the purpose of imparting a step by step movement to the power rollto sucw cesslvely bring the different designations upon the indicatingsheet into view, 1 provide the following described actuating mechanism.Rotatably supported upon the shaft 12 is an upwardly extending arm 17.The arm 17 has central pivotal connection 18 with a horizontal bar 19,the bar 19 at its opposite ends being pivotally connected to thearmatures 20 and 21, respectively, in sliding position in connectionwith the magnets 22 and 23, respectively. The free end of the lever arm17 has pivotal connection 24 centrally with transverse bars 25 and 25.The bars 25 and 25 at their ends have spring connections 26 and 26 withthe bracket 9. Having fulcrum support 27 and 28 on the bars 25 and 25 atpoints between the inner sides of the springs 26 and 26 are lever arms29 and 30. The lever arms 29 and 30 at their lower ends are pivotallyconnected respectively with the armatures 31 and 32 slidably arranged inconnection with the electromagnets 33 and 34. The lever arms 29 and 30are formed at their upper free ends with the fixed 36, respectively, andalongside said dogs 35 37 and 38, respectively.

Fixedly mounted upon a shaft 39 intermediate of a notched disk 40 andbehind the same a pair of toothed disks 41 and 42, a spur wheel 43 beingsecured upon the shaft behind the toothed disk 42. The spur wheel 43engages with a pinion 44 mounted upon the shaft 12 of the power roll,whereby the rotation of the spur wheel 43, as hereinafter described,will rotate the shaft 12 and the supported power roll. The shaft 12supports the pivotally supported and 36 are the dogs ratchet wheel 45,in connection with the 0pposite sides of which work spring pressed pawls46 and 47. The lever arm 17 at its lower end carries a lug 48 to engagewith one or the other of said pawls, as the arm 17 is turned, so thatone of the spring pressed pawls will normally stand in engagement withthe ratchet wheel to hold the shaft of the power roll from turningbeyond the amount turned by the spur wheel. The rollers 2 and 6 are heldunder spring tension by means of springs 49 and 50, each being connectedat one end with a spur wheel dogs 35 and the roll 6 and the power rollis 51 and having pinion connection 52 with the shaft of the adjacentsupply roll.

The dogs 35 to 38 are so positioned that when the bars 25 and 25 aremoved to the left, as shown in Fig. 2, the dog 38 will fit into theserrations of the disk 40 and the dog 36 will engage with the teeth ofthe disk 41. The spring pressed dogs 37 and 38 simply act as lookingdogs to hold the shaft 39 from forward movement beyond the point wherethe shaft is rotated by the dogs 35 and 36. When the bars 25 and 25 inthe operation of the apparatus are moved to the right, the dogs 36 and38 will be released and the dog 37 will be carried into the serrationsof the disk 40.

For the purpose of bringing about a reverse movement of the indicatingsheet, as hereinafter particularly described, I provide a verticallydisposed arm 53 having central fulcrum support 54. The upper free end ofthe lever arm 53 stands alongside the indicating sheet. The lower end ofthe arm 53 has sliding connection with the upper end of a lever 55, thelever 55 having central fulcrum support 56. The lower end of the lever55 has pivotal connection 57 with a lever arm 58. The free end of thelever arm 58 stands alongside of the indicating sheet, the lever armcentrally resting upon an extension 59 of the bracket 4. The end of theindicating sheet adjacent to the roll 2 carries a lug 60 for the purposeof engaging with and actuating the lever 58, as hereinafter pointed out,to bring about reversing of the apparatus, as the unwinding of the sheetfrom the roll 2 and winding up upon the roll 6 is completed. There isalso a similar lug 60 carried by the opposite end of the sheet to engagewith the end of the lever 53 and actuate the same when the sheet isoppositely wound up upon the roller 2.

For the purpose of bringing the electric current from the overheadtrolley wire B to th electromagnets I provide the following combinationof parts. Depending from the trolley wire B at predetermined points arethe contacts 61 which as the trolley wheel 62 passes, will brush thecontact 63 supported by the trolley pole 64. A conducting wire 65 leadsfrom the contact 63 through the easing to the magnet 23,.the and 33being in circuit. The electromagnet 22 is electrically connected withthe electromagnet 34 through the wiring 68 and 70. Arranged inconnection with the lever arm 53 are the jack knife switch members 71and 7 2, which are electrically connected with the electromagnets 22 and34. Similar jack knif switch members 73 and 74 are electricallyconnected with the electromagnets 23 and 33. The wiring is groundedthrough the ground wire 75.

In operation, wound from the roll as the sheet becomes unis' just ,saidmotor being operatively electromagnets 23 v 'struction strikes the lever2 to the roll 6, the stop 60 will strike the lever arm 58 and throw' theswitch members 73 and 74 into contact. As soon thereafter as contact ismade between the contacts 61 and 63, the magnets 23 and 33 will beenergized to move the dog 36 out and-the dog 35 into contact with thecorresponding toothed wheel through the medium of the magnet 23, themagnet 33 imparting a step by step movement to the ratchet wheel 43 tocorrespondingly move theindicating sheet. When the opposite end of theline is reached the lug 60 at the other end of the sheet will strike thelever arm 53 and by closing the switch members 71 and 72 and openingswitch members 73 and 74 bring about the reverse travel of the sheet.

The modification shown in Fig. '5 is de: signed to be used in connectionwith a railway loop where the cars continue to go in the same directionand where at the end of the loop, instead of reversing the direction oftravel of the indicating sheet, it is necessary to rewind the sheet sothat it may be again fed from the feed to the receiving roll during Inthe form shown in Fig. 5 the construction exactly like that shown inFig. 2, with the exception that the clectromagnet 33 is left out,inasmuch as it is only necessary to use the electromagnet 34 to impartstep by step movement to the sheet actuating parts in one direction.When, in the modified construction, the car reaches the end of the loop,and the sheet becomes unwound, the stop 60 carried by the sheet actuatesthe lever arm 58, and through the action of the magnet 23 carries theactuating dog out of the next trip around the loop. 7

engagement with the toothed disk and brings the contactmembers 76 and 77into contact. As will be noticed by referring to Fig. 5, the contactmember 77 is fixed, and the contact member 76 is carried by the slidablebar 19. The contact members 76 and 77 when closed start the motor 7 8,.and connected through gearing 79 with the delivery roll, causes therewinding of the indicating sheet thereon. As soon as the sheet is fullyrewound upon the delivery roll, the stop 6O carried by the opposite endof the sheet in the same manner as in the preferred con- 53 to throw theelectromagnet 22 into electrical circuit'and separate the contacts 7 ,6and 77 throwing the motor out of action and leaving the indicating sheetready to be carried in a step by step movement from they delivery to there ceiving roll during the next trip of the car.
